Chemistry of s, p, and d Block Elements — A/L Chemistry

The periodic properties and chemical reactivity of s, p, and d block elements correlate directly with their valence electron configurations, oxidation states, and coordination chemistry.

1. Group Trends (s & p blocks): Explaining periodic variation in atomic radii, ionization energies, electronegativity, flame test colors, and thermal decomposition of nitrates and carbonates.
2. Transition Elements (d block): Characteristic properties of transition metals: variable oxidation states, catalytic activity, magnetic properties, and colored complex ion formation.
3. Coordination Complexes: Naming complex ions by IUPAC rules, identifying coordination number and ligand denticity, and explaining color origins via d-d electronic transitions in split d-orbitals.
